Serpentine Cabachon and Bare Copper Pendant

I have bezel set a 9mm diameter Green Serpentine cabachon into a Bare Copper collet .  This I have attached, in an off center position, to a 29mm diameter ring of bare copper to which I have given a hammered effect.  The pendant is suspended, using a copper bail, from a veneered leather cord which is finished with a base metal clasp and extender chain.
